Specification of Letters Patent. Application filed August 11, 1905.Serial No. 273.735.

Patented July 17, 1906.

To all whom it may concern:

Be it known that I, PEMBERTON DUDLEY, a citizen of the United States,and a resident of .Asbury Park, in the county of Monmouth and Stateof.New Jersey, have invented a new and Improved Trolley-Role, of whichthe following is a full, clear, and exact descri tion.

T e purpose of the invention is to provide a ball-and-socket connectionbetween the laterally-curved guide and fork, which construction is 'sieconomic,

and effective and allows the trolley-wheel to accurately follow the wireeven when the wire is not exactly overhead and alsoto follow the wireupon all manner of curves, said construction also insuring the wheelbein straight'upon the wire regardless of the angle of the pole.-

The invention consists in the novel consuplport for the mp e I structionand combination of the several parts, as will be hereinafter fully setforth,

and pointed out in the claims. v M

' Reference is to be had to the accompanying drawings, formin a part ofthis specification, in which simi ar characters of'reference indicatecorresponding parts in all the figures. p

Figure 1 is a front elevation of the upper end of a trolley-pole, thefork-holder, and, fork, showing the latter in two positions. Fig. 2 is avertical section taken substantially on the line 2 2 of Fig. 1; am. Fig.3 is a sectional plan view, of the device, the section 11% g takensubstantially on the line 3 3 of i'represents the trolley-pole, and Bthe support connected with the trolley-pole and adapted as'a g'uide, aswell as a support,for the fork-G, The support Bis hollow and in generalcontour ,is similarin outline to the outline of an inverted triangle,the side ed es extending outward and upward in opposite directions fromits contracted end, and the upper and wider end is open and is renderedmore or less convex, whi contracted end of the aid combined guide duced,as. is shown in Fig. 2. The combined guide and support B is made "aslight gas ipossible {consistent iwith fork for the trolley wheel and thepole and a In order that-the fork centrally located with respect to theholder,

e at the lower and and support B a circu ar socket 10 is prostrengthandis constructed in two sections 11 and 12, the dividing line beingcentrally and longitudinally located. The section 11 is integral withthe pole A; but the section 12 has a hinged connection 14 with the pole,as is shown held together by forming lugs 13 and 13" at the centralportions of the side faces A of the said sections and passing bolts 14through said lugs.

In addition to the eculiar fan or angular formation of the com inedholder and guide B the said holder or guide is laterally curved, its oneface 15 being concaved and the opposing face 16 convex, as is shown bestin Fig. 3. The socket 10 is partially in one section and partially inthe other section of the holder. Thetrolley-Wheel 17 is mounted to turnin the usual manner in the fork O, and the said forkC is provided witha-downwardly-extending stern 18, substantially rectangular in. crosssection. The said stem asses loosely down through the said holder be ingada ted for-tree lateral movement in the said he der, ball 19, mountedloosely "in ,the aforesaid socket 10. It will be understood that anyapproved means provided.

as is shown by full lines in Fig. 1, springs 28 bear againstoppositecurved sides o the shank or stem 18 of the fork, which springsare located within the holder B and aresecured to the side walls of thesaid holder near its lower end by bolts 21 or their equivalents.

When a trolley-pole has the above-de scribed improvements applied,v thetrolleywheelis bound to follow the wire even when the wire is notexactly overhead and will,

positively follow the wire under all manner of curves. thirty degrees tothe car the curvature in the fork-holder will permit the wheel to stillkeep straight on the wire and not ca'nt'in direction of the pole. i I

Having thus described my invention, I claim as new and desire tosecureby Letters Patent in Fig. 1, and the two sections are as the-said stemterminates in ao se n be was,

for oilingthe ball may be Even if the pole is at an angle'of 1. Atrolley-pole, a trolley-fork having a tending from the ,bztll-rrndsocketconnection with and a holder in Winch-the fork has guide-d movement,said holder being lotemll'y curved 35A trolley-pole, a substantiallytrihngw lorly-slmped hollow holder having its contracted endconnectodwith the pole, being open at the top and provnml f-t circularsocket at its bottom portion, one side the said holder being concovedand the other convezied, e trolley-Wheel fork, o slnml': e2:-
